For the following pseudo-code determine number of tests required for 100% statement coverage IF Gender = Boy If Age > 3 AND Age < 5 Shoe Size = 1 ELSE IF Age >=5 AND Age < 7 Shoe Size = 2 ENDIF ELSE…

Question

Options

• A6
• B4
• C2
• D6

• A
  11% (4)
• B
  57% (20)
• C
  6% (2)
• D
  26% (9)

Explanation

To achieve 100% statement coverage, we need to design test cases that ensure every statement in the given pseudo-code is executed at least once. Analyzing the pseudo-code, we notice that there are conditions based on two variables: Gender and Age. To cover all statements, we need to consider the paths that lead to each assignment of the Shoe Size variable. Gender = Boy, Age <= 3 (Shoe Size assignment is not reached, but the condition is evaluated) Gender = Boy, Age > 3 AND Age < 5 (Shoe Size = 1) Gender = Boy, Age >= 5 AND Age < 7 (Shoe Size = 2) Gender != Boy, Age <= 3 (Again, Shoe Size assignment is not reached, but the condition is evaluated) Gender != Boy, Age > 3 AND Age < 5 (Shoe Size = 0) Gender != Boy, Age >= 5 AND Age < 7 (Shoe Size = 1) However, upon closer inspection, we see that tests 1 and 4 do not contribute to statement coverage as they do not lead to a Shoe Size assignment. Therefore, we only need 4 test cases to achieve 100% statement coverage, making option B the correct answer.
